Recommended UTM parameters for newsletters
Use a source that identifies the newsletter, publication, or sending system,
and use email as the medium. Give each send or sequence a recognizable
campaign value such as weekly_digest, product_update, june_newsletter,
black_friday_email, or onboarding_email_1. Lowercase values are easier to
filter and less likely to split reports.
Source and medium answer different questions
utm_source answers which sender or program produced the visit. It might be
newsletter, mailchimp, substack, convertkit, klaviyo, beehiiv, or hubspot.
utm_medium answers which channel carried it, usually email. Keeping the medium
stable lets you compare total email traffic while the source provides a more
specific breakdown.
utm_source=newsletter&utm_medium=email&utm_campaign=weekly_digest
Use utm_content for links inside the email
A newsletter often links to one destination several times. Use content values
such as header_cta, footer_link, product_card, text_link, or banner to measure
which placement was clicked. Keep source, medium, and campaign unchanged so
all links still roll up to the same send.
Avoid duplicate automatic tagging
Some email platforms can append campaign parameters automatically. Review
those settings before pasting manually tagged links, because competing values
may overwrite your convention. Send a test email, click each important link,
and confirm the destination and parameters. This tool only builds URLs; it
does not send email or connect to subscriber data.
